On the Metabolism of Carotenoids in the Crustacean Artemia salina

Zeitschrift für Naturforschung B, 1968
Die Zusammensetzung und der Stoffwechsel der Carotinoide in adulten Exemplaren von Artemia salina wurden untersucht. Unabhängig von der Fütterung mit carotinoidfreier Hefe, mit an Oxicarotinoiden reicher Nahrung oder mit Oxocarotinoid-haltigen Algen lassen sich als Hauptpigmente Canthaxanthin (4.4′-Dioxo-β-carotin) und Echinenon (4-Oxo-β-carotin ...

DEET‐cyclodextrin inclusion complexes for mosquito and tick repellency: Extended repellency time and no zebrafish embryotoxicity

Pest Management Science, EarlyView.
Hydroxypropyl‐β‐cyclodextrin (HPβCD)–N,N‐diethyl‐meta‐toluamide (DEET) complex extended tick repellency to 168 h. Full protection against Aedes aegypti for 7 h with HPβCD‐DEET. HPβCD reduced DEET release and skin retention significantly. No embryotoxicity observed below 325 mg L−1 in zebrafish model.

Rotenone Induces Morphological Damage and Reduction in Catecholamine Levels in the Central Nervous System of the Ascidian Styela plicata

Environmental Toxicology, EarlyView.
ABSTRACT Ascidians are invertebrates that occupy a key phylogenetic position as a sister group of the vertebrates. The organization of their central nervous system (CNS), with cortex and medulla, indicates a plesiomorphic character of the gray and white matter of vertebrates, making this group of animals useful for studies of neurodegenerative events ...

Artemia salina Toxicity Assay: Standardization in a 24‐Well Microplate

Environmental Toxicology, EarlyView.
ABSTRACT Bioassays with Artemia sp. are widely used in aquatic, environmental, and human toxicology as an initial tool to investigate the toxicity of plant extracts, isolated compounds, drugs, and products of natural or synthetic origin. These assays allow for the estimation of the median lethal concentration (LC50) and guide subsequent studies in ...
